Abstract

Wheat (Triticum aestivum), durum (Triticum turgidum ssp.durum), barley (Hordeum vulgare), and oats (Avena sativa)are susceptible to infection by the crown rot pathogenFusarium pseudograminearum (1). This study describesthe differences in infection levels of F.pseudograminearum in bread and durum wheat, barley,and oat internodes using a species specific quantitativePCR (qPCR) assay and relates the average amount offungal DNA found in the internodes to the average visualratings of the internodes based upon a severity scale (2).
